Black Ops II "Liberation" DLC fake

It seems to be that time again where the fake DLC leaks start coming out. This recent one for Call of Duty: Black Ops II, Liberation, appeared legit. With good art, unique design and names, and even a correct release date (if previous leaks are to be believed).

So what makes it blatantly obvious the the DLC is fake? Well, the Zombie on the right is from The Walking Dead. That's a start.
